Both wind power and photovoltaic power generation have the common advantages of being clean, renewable, and never exhausted. Wind power generation has more obvious advantages than photovoltaic power generation. Why do you say this? Mainly based on the following two points:
1. The cleanliness of photovoltaic power generation is relative, because the production of solar panels has the characteristics of high pollution and high energy consumption, and the manufacturing process is not environmentally friendly; while the cleanliness of wind power generation Cleanliness is absolute, which has obvious advantages over photovoltaic power generation!
2. After all, the energy distribution density of photovoltaic irradiation is small. To generate a large amount of electric energy, it takes up a huge area. Therefore, solar power stations generally occupy a relatively large area. A 1GW photovoltaic power station requires an area of 300-400 square meters. acres, so photovoltaic power stations are generally built in remote areas with vast land and sparsely populated land and barren land (it is impossible to build photovoltaic power stations on farmland in densely populated areas). Wind energy power generation facilities occupy a small area and have little impact on normal farming of farmland. Especially offshore wind power does not need to occupy land!
Wind power and photovoltaics have obvious seasonality and fluctuation. The proportion of wind power and photovoltaic power generation
Photovoltaic.
In daily life, there are many photovoltaic application scenarios. For example, rural rooftop photovoltaics, or fishing-light complementary photovoltaics, or roadside street lamps equipped with solar power panels, etc. The size of the photovoltaic power generation panels can be changed according to different application scenarios. It can be said that photovoltaic application scenarios are the most extensive. As for wind power generation, the most common ones are huge wind turbines standing in the fields.
The impact of this proportion is as follows:
1. Wind power is usually stronger in spring and autumn, so the amount of wind power generated in these two seasons will increase. Relatively high, in summer and winter, due to weakened wind power, wind power generation will decrease accordingly; photovoltaic power generation is higher in summer and sunny days, because the sunshine time is long and the intensity of solar radiation is high. In winter and cloudy days, photovoltaic power generation will decrease.
2. The volatility of wind power and photovoltaic power generation is mainly affected by weather conditions, such as changes in wind speed, cloud cover, etc., which will lead to unstable power generation.
